Abstract(s)Arthrobacter viscosus biomass was used for Cr(VI) biosorption. The effect of biomass concentration on Cr(VI) reduction and removal from aqueous solution was studied in the range of 1.2 to 5.3 g/L. The removal of Cr(VI) and total chromium increased linearly with the increase of biomass concentration. The best removal efficiencies of Cr(VI) and total chromium were reached for the highest biomass concentration, 72.2 % and 44.0 %, respectively. The increase in biomass concentration did not produce significant changes in the uptake values. The maximum uptake value, 8.2 mgCr/gbiomass, was obtained for a biomass concentration of 2.3 g/L.
